Party girl Meg Highbury wakes up the morning after her twenty-first birthday with one hell of a hangover—and a walking corpse in her apartment. Meg turns to her straight-laced neighbor Armando for help, and together they discover that Meg is a Valkyrie. What’s more, her first duty is to trade places with the corpse.
But Meg is being sent to her Death Duty too soon. In a race against time, Meg frantically tries to find a loophole to avoid her gruesome fate, but while Meg is determined to live whatever the cost, Armando's strict moral principles keep getting in the way of her plans for escape.
Can Meg walk the “right” and narrow path, possibly sacrificing her mortal life, for love? And if she can, will Armando have the stomach to love a rotting corpse of a girl who is falling apart in more ways than one?
